BACKGROUND ART

The stone for nail decorations, in general, used during a nail art work is small in size and flat, for which it is hard to pick up each stone with a hand or move it. Since a stone should be accurately positioned on the upper surface of a nail having a relatively narrow space, so an accurate work is inevitably necessary.

As illustrated in FIGS. 1A and 1B, a nail art work is frequently carried out while picking up and moving each stone using a predetermined tool. FIG. 1A illustrates tongs which is able to pick up and move a small thing, and FIG. 1B illustrates a stone pencil (a stone picker pencil) which is able to attach a stone at its end and then move. As for the aforementioned stone pencil, it is shaped like a pencil, wherein a core portion is made of a predetermined material, for example, a wax, etc. If a stone contacts with an upper surface, a stone can be attached to a core portion.

In case of the aforementioned tongs, it needs to continuously use a gripping strength when picking up each stone, and a very accurate work is necessary to pick each stone. For this reason, the frequency of uses of the tongs becomes lower and lower as compared to a stone pencil. As for the stone pencil, the attachment of a stone may fail easily, and a stone which has been attached to a desired position of a nail, sometimes, won't separate from the tip of the stone pencil.

When it needs to use such tongs or a stone pencil, a work to individually pick up a stone and contact the picked stone to the core of a pencil is required after a stone for decoration has been spread over a work table. In this case, stones may be lost. A more accurate and complicated work should be carried out so as to pick up and move stones if stones have been turned upside down.

Meanwhile, in order to prevent the loss of the cover 20, the cover 20 can be used engaged to a lower portion of the pencil handle 10 after it has been separated. Here, an engaging groove 114 may be formed at a lower end portion of the pencil handle 10 for the sake of an easier engagement of the cover 20.

FIG. 4 is a schematic cross sectional view illustrating the configurations of a supply part 14 and a discharge part 15 of a stone pencil 1 for nails according to the present invention. FIG. 5 is a schematic cross sectional view illustrating the configurations of a supply part 14, a discharge part 15, and a button 16 in a state where a cover 20 is inserted at an end portion of a stone pencil 1 for nails according to the present invention. FIG. 6 is an enlarged view illustrating the portion “A” in FIG. 5.

As illustrated in the drawings, the pencil handle 10 may include a receiving part 12 formed inside of the cylindrical main body so as to accommodate stones for nails. The receiving part 12 is configured to supply the stones for nails to the discharge part 15 via the supply part 14 based on an activation of the button 16.

Referring to FIG. 6, the receiving part 12 may include an inclined part which is tapered more and more in the direction of its top which is connected to the discharge part 15, wherein the diameter of the receiving part 12 is decreased similar to the diameter of the cylindrical configuration which forms the discharge part 15 at the top thereof. The top of the receiving part 12 is connected to the discharge part 15, so the inner spaces thereof communication each other.

The discharge part 15 may include a pencil tip part 151 which protrudes to the outside of the pencil handle 10, and a connection part 152 which is accommodated inside of the pencil handle 10. The connection part 152 is configured in a cylindrical surface configuration to accommodate therein a supply part 14 which will be described later. The tops of the pencil tip part 151 and the receiving part 12 contact with each other via the connection part 152. Here, the connection part 152 includes a connection groove 153 at a portion corresponding to the top of the receiving part 12, so the top of the receiving part 12 can communicate with the inner space of the connection part 152 via the connection groove 153.

The supply part 14 is accommodated inside of the connection part 152 of the discharge part 15, and the supply part 14 may include receiving groove 141 which is formed in circular plate shapes each having a predetermined thickness and are arranged at regular intervals along an outer circumferential surface. The supply part 14 is connected rotatable inside of the connection part 152 and is configured to rotate at a predetermined angle whenever the button 16 is touched. For example, in case of the supply part 14 illustrated in FIG. 6, a predetermined receiving groove 141 may communicate with the top of the receiving part 12 via the connection groove 153 before the button 16 is touched, it will receive the stones for nails from the receiving part 12 and store them.

Thereafter, the supply part 14 will rotate in a counterclockwise direction in response to the touch of the button 16, and it will rotate to a position contacting with the pencil tip part 151 by the third touch of the button 16, so the stones for nails can be supplied to the pencil tip part 151. In the embodiment of the present invention, while the receiving groove 141 has been described as being provided six in number, it is obvious that the receiving groove 141 can has various configurations for them to be disposed at the positions contacting with the pencil tip part 151 whenever the supply part 14 rotates.

The receiving groove 141 may be configured to receive and accommodate the stones for nails at the moment it becomes communicated with the top of the receiving part 12 via the connection groove 153 when the supply part 14 rotates. Moreover, it is preferred that the receiving groove 141 can be configured to correspond to the shape of each stone for nails so that the top of each stone for nails can contact with the inner side surface of the receiving groove 141, and the bottom of each stone for nails is disposed toward the outside of the receiving groove 141. For example, if a stone for nails has a flat bottom and a convex top, the inner side surface of the receiving groove 141 may be formed concave to correspond thereto, by which the convex top of the stone for nails can be accommodated contacting with the inner side surface of the receiving groove 141. In this way, the receiving direction of the stone for nails can be determined based on the shape of the receiving groove 141. When the stones for nails accommodated in the receiving groove 141 is provided to the pencil tip part 151 as the supply part 14 rotates, the bottom of each stone for nails is first discharged. Subsequently, if the stone for nails is supplied in a state where an end portion of the pencil tip is closer to the surface of a nail, the stone for nails can position in the normal direction wherein the stone for nails is not inverted.

A guide 115 protruding toward the center may be provided at an inner side surface of the pencil handle 10 so as to fix the positions of the discharge part 15 and the receiving part 12, and the movement of the inclined part of the receiving part 12 toward the top is limited by the guide 115. Moreover, circular protrusions 154 and 161 the diameters of which are larger than the holes at the top of the pencil handle 10 may be provided at an outer circumferential surface of the pencil tip part 151, so the movement of the discharge part 15 toward the backside of the pencil handle 10 can be limited by the circular protrusion 154.

The button 16, as mentioned earlier, may be disposed near the top of the pencil handle 10, and may be preferably disposed more behind the position where the connection part 152 is accommodated. Near the top where the button 16 is disposed, an opening part 110 may be formed at a part of the outer circumferential surface, and an elastic member 17 may be engaged to the opening part 110. The button 16 may be connected to an outer end portion of the elastic member 17. If the button 16 is pressed in the direction of the outer circumferential surface of the pencil handle 10, the elastic member 17 will be pressed by the button 16, and the supply part 14 connected thereto will rotate about the axis of the circular plate part, thus moving the position of the receiving groove 141.

Moreover, a protrusion part 111 may be formed at an outer circumference of the opening part 110 where the button 16 is disposed. A shoulder part 112 may be provided between the protrusion part 111 and the opening part 110. Furthermore, an elastic member 17 is connected in the center at an inner end of the button 16, and a protrusion part 161 may be formed at an outer circumference of the portion where the elastic member 17 is disposed. A groove part 162 may be formed at an outer circumference of the protrusion part 161. The groove part 162 of the button 16 may position corresponding to the protrusion part 111 formed at an outer circumference of the opening part 110 of the pencil handle 10. If the button 16 is pressed, the protrusion part 111 of the pencil handle 10 is inserted into the groove part 162 of the button 16, thus applying a pressure.

At this time, if the cover 20 is engaged so that the lower end portion of the cover 20 engaged to the top of the pencil handle 10 can be disposed between the inner end portion of the button 16 and the pencil handle 10 corresponding thereto, the pressing of the button 16 can be limited. In this way, if the stone pencil 1 for nails is not used, it is possible to prevent the stones for nails from gathering in the inside of the cover 20 due to the user's unintentional operations of the button 16.

FIG. 7 is a schematic cross sectional view illustrating a configuration which corresponds to the backside in FIG. 6 and a configuration wherein a supply part 14 rotates when a button 16 is pressed. The operation wherein the position of the accommodation is moved as the supply part 14 rotates when the button 16 is pressed, will be described with reference to the drawing. First, a pressing member 18 extending into the inside of the pencil handle 10 is provided at an inner end of the button 16 of the present invention. Whenever the button 16 is pressed by a pressing end part 19 which corresponds to an end portion of the pressing member 18, the supply part 14 is pushed in the direction of rotations, thus rotating it.

A toothed part 142 protruding outward may be provided in at least one among the circular plate parts of the circular plate-shaped supply part 14. The toothed part 142 may have a predetermined number of teeth or protrusion parts which correspond to the receiving groove 141 formed at an outer circumferential surface of the supply part 14. Whenever the pressing member 18 moves in the direction of the center of the main body of the pencil handle 10 by the button 16, the teeth will move in the direction of the rotation by the pressing member 18, thus rotating and moving the whole portions of the supply part 14. Here, it is preferred that the pressing end part 19 is formed in a hook shape which is formed concave in the contacting direction with the toothed part 142 lest it does push the toothed part 142 in the reverse direction.

Moreover, in order to limit the scope of movements of the pressing end part 19, a support plate-shaped first stopper 155 may be provided at the connection part 152 at a contacting position with the pressing end part 19 in a state where the button 16 has been pressed. The lower end portion of the first stopper 155 is able to prevent the pressing end part 19 from moving excessively.

Furthermore, in order to prevent the toothed part 142 from rotating excessively due to the operation of the button 16, a bent plate-shaped second stopper 157 may be provided at an inner side of the connection part 152. Since the teeth of the toothed part 142 can be substantially supported by the second stopper 157, it is possible to prevent the toothed part 142 from moving excessively by means of a weak pressure. The second stopper 157 may be fixedly installed using a predetermined fixing part 156 which is provided separate at the connection part 152.
